15. Power up test / Control card test
The diagnosis of the Drive consists of two tests:
Power up test
Extended CC test
The Power up test is carried out every time the Drive is powered up and consists of:
Checksum validation of calibration data stored in EEPROM
Checksum validation of hardware and motor dependent parameters in EEPROM
The extended power card test can be activated via the parameter 620 and consist of:
Checksum validation of calibration data stored in EEPROM
Checksum validation of hardware and motor dependent parameters in EEPROM
Flash check
I/O test
